Latest Patents

Freitag's latest patents focus on innovative methods and apparatuses for joining shaped bodies of polytetrafluoroethylene. One of his patents describes a method for joining edge surfaces of PTFE material using a butt joint. In this method, abutting surfaces are placed in a chamber bounded by clamps that press the surfaces together. Heating elements within the chamber heat both sides of the material, while the chamber's boundaries inhibit volume expansion during heating. Additional pressure is applied during the cooling phase to ensure a strong joint. Another patent outlines a similar method, where heating means are spaced from the clamps, utilizing radiation or convection to heat a strip between them. A thin foil of a fluorine-containing thermoplastic is used to facilitate the joining of surfaces.
